Description

The MasterStudy LMS WordPress Plugin – for Online Courses and Education plugin for WordPress is vulnerable to unauthorized access of data via the 'wpcfto_get_image_url' AJAX action in all versions up to, and including, 3.7.56, due to a missing capability check and missing nonce verification on the bundled NUXY settings library's wpcfto_get_image_url() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve the URL of any media attachment by ID, including attachments that belong to private or draft posts.
